yes, era is not what I am looking for. I used to tag the time component (in rare cases) with the key "period", e.g. period=aurelian for one of the city walls of Rome: http://en.wikipedia.org/wiki/Aurelian_Wall. cheers, Martin _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
